Karl

Good info. Thanks. 

In the case I cited, an auxiliary centerline fuel take for the A310 had been certified by EASA but not by the FAA. The aircraft was acquired new by Austrian. Some assumed FAA cert was automatic by virtue of the EASA cert, but the FAA reserved its own separate certification authority over fuel tanks.  As a result the aircraft could not obtain an FAA certificate of airworthiness without subjecting the aircraft (actually, the installation/process) to separate FAA approval processes.

Scott,

JetBlue has been flying the A321LR for several years so all three ACTs must have FAA certification.

The FAA had concerns about the A321XLR’s RCT:


If memory serves, these concerns were ultimately addressed by adding additional belly material to reduce risk in the case of a belly landing. In any case, the A321XLR with CFM engines received FAA certification on 2 October 2024:


Certification with P&W engines followed in December 2024:


Given the importance to Airbus they wouldn’t have let it slip the way they did with the A310!

Are all of those auxiliary fuel tanks on the A321 FAA certified?

That question played a central role in Austrian Airlines v UT Finance Corporation, 567 F.Supp.2d 579 (https://www.courtlistener.com/opinion/2456814/austrian-airlines-oesterreichische-luftverkehrs-ag-v-ut-finance-corp/), that 2008 case involving an Airbus A310-324.

Keady and Eric,

I couldn’t find a good set of specs on the Airbus site so resorted to Wikipedia:


Airbus offers optional Additional Centre Tanks (ACTs) which hold 3,121 liters (824 US gallons). Up to two can be fitted in the aft cargo hold; the  A321XLR adds a third one in the forward cargo hold.

The A321XLR features a Rear Centre Tank (RCT) which has slightly more than four times the capacity of an ACT whilst weighing the same as an ACT and occupying the cargo space of two ACTs. An optional forward ACT can also be fitted.

A A321XLR with the optional forward ACT has the same cargo capacity as an A321LR but without that option it has room for one more LD3-45.

With regard to Eric’s comment about cargo rates down under, I suspect one difference is that there’s far more capacity in the US, especially when you consider one-stops between the coasts. There’s not much in the middle of Australia so except for shorter routes along the east coast most flights are transcons or nearly so.

I thought cargo space on the XLR  was sacrificed for extra tanks.  Keady


On Tue, Jul 1, 2025 at 15:46, ERIC Smith via Mifnet
According to Bob Crandall, "There's no money in cargo." So it surprises me that there would be enough extra cargo capacity on the XLR vs the NEO to make a difference. Are cargo rates in Aussieland that much higher than in the US that cargo revenue is a rational choice for the XLR decision?
